Hi I have a question on the best way to form a small section of concrete in an overhang area. It's probably easier to see a picture so here goes:
Where I labeled the word "Here" is where I am having trouble. I need to form a strip of concrete overhang along the top edge of the window, over the wood framing. I need to do this because there are three other equivalent size existing windows that looks like that along that wall so I need to match it.
I can see screwing a 2x4 along the bottom edge of that concrete, do I just then scoop concrete into the slot until it fills up and finish it flat? Seems this would be difficult to do I remember last time I was doing this there were more spillage on the ground then there is in that narrow space.
Someone mentioned to me to have a piece of wood at the bottom, then spray in those foam to fill up the space, not all of it but most of it, then use concrete to fill in the rest?
Thanks in advance,
MC
